+# =============================================================================
+# Two-Stage Dependency Installation Strategy
+# =============================================================================
+#
+# This Dockerfile uses a two-stage installation approach to optimize Docker layer
+# caching and reduce rebuild times when source code changes.
+#
+# Stage 1 (below): Install heavy framework dependencies
+#   - Installs large ML frameworks (SKRL, JAX, PyTorch, TensorFlow) (~3GB)
+#   - Skips workspace members (motrix-envs, motrixsim) that depend on source code
+#   - These dependencies rarely change, so this layer is heavily cached
+#   - Mounts only configuration files (pyproject.toml, uv.lock), no source code
+#
+# Stage 2 (after source copy): Install workspace members and remaining dependencies
+#   - Installs all workspace members (motrix-envs, motrix-rl, motrixsim)
+#   - Source code changes only invalidate this stage, not Stage 1
+#   - Significantly faster rebuilds during development
+#
+# Benefits:
+#   - Source code changes don't require re-downloading 3GB+ of dependencies
+#   - Dependencies are cached across builds using UV cache
+# =============================================================================
